Patented Feb. 27, 1934 UNITED STATES PATENT OFFICE 12 Claims.

This invention relates to improvements in windows and it has particularrelation to a window construction wherein slides having sashes mountedon them are adapted to be moved vertically in stile grooves.

The main objects of the invention are to provide a window constructionin which the sash is pivotally mounted on a slide and adapted to bemoved about a horizontal axis and swung inwardly to a slight extent forthe purpose of ventilation; to provide a window construction that whenopened for ventilation the sash portion thereof is maintained in lockedrelation with the frame portion thereof; to provide a plurality of meansfor maintaining said sash in position for ventilation, said meansoperating in conjunction with each other to prevent inadvertent openingof the window to a substantially horizontal plane; to provide a windowconstruction in which certain elements co-act to form an exceptionallyweatherproof window.

The above being among the objects of the present invention, the sameconsist of certain features of construction, combination of parts to behereinafter described with reference to the accompanying drawings andthen claimed, having the above and other objects in view.

For a better understanding of the invention, reference may now be had tothe accompanying drawings, forming a part of this specification, inwhich:

In the particular embodiment of the invention disclosed in the drawingsa window frame 10, is provided with stile grooves 11 and 12 formedtherein. As shown in Fig. 3, the grooves 11 and 12 are formed by spacedmembers 13 and 14, rigidly secured to opposite sides of the frame andlongitudinally thereof in any suitable manner, such as screws 15, eachportion having an inwardly extending flange 16, and by parting stripmembers 1'7 disposed midway between the members 13 and 14 and secured tothe frame by screws 19. The parting strips 1'7, are provided with flangeportions 18 extending toward the flanges 16, the surface of the flanges16 and 18 adjacent the frame 10, being disposed in alignment withrespect to each other.

Vertically slidable in the grooves 11 and 12 are upper and lower slideportions 20 and 21 respectively each of which are provided with portions22, extending at right angles from the main body portion 23 thereof, toform members substantially of channel section, the open sides of whichare disposed outwardly with respect to the frame 10. Each of theportions 22 may be provided with shoulder portions 24, extending thefull length of the rear margin and adapted to fit in grooves formed bythe frame 10 and the flange portions 16 and 18. These coacting flangesand grooves form a weatherproof joints for the window. Relativelyflexible metal strips 25, disposed between the parting strips 1'7 andthe frame 10 are provided with portions 26 extending between the flanges18 and the shoulder portions 24 and are provided therefor to assist informing a particularly efficient weatherproofing joint adjacent theparting strip 17. The slides 20 and 21 may be provided with inwardlyprojecting flanges 2'7 and 28 respectively which extend the full lengthof the outer margin. Disposed. against the flanges 2'7 and 28 are sashplates 30 and 31 respectively, each having inwardly extendinglongitudinally disposed ribs 30a and 31a. The rear edges of the sashplates abut the flange portions 27 and 28 respectively, when theirsashes 32 and 33, secured rigidly to the sash plates 30 and 31, aredisposed in a vertical plane. A pair of grooves 34 and 35 are formedadjacent the inner margins of the slides 26 and 21 respectively and areprovided to receive outwardly and rearwardly extending projections 36and 37 on the plates 30 and 31 respectively, so that the cooperatingportions function as weatherstripping when the sashes are verticallydisposed. Portions 38 and 39 of the sashes 32 and 33 are each providedwith angularly disposed surfaces, having an ofiset portion thereon toform a weatherproof joint as indicated at 40.

As the mounting of the upper and lower sash plates and their slides areidentical, I will now describe in detail the mounting of the lower sash33 on the slide 21, reference being had to Figs. 4 to 10 of thedrawings.

Extending outwardly from the sash plates 31 adjacent their lowerextremities are hinge pins 42, extending through the lower end of theslides 21 and are held in position in any suitable manner. Pivotallymounted within the channel shaped portion of the slides 21 andintermediate of their length are resilient spring-like members 43, whichare provided to support locking pins 44, extending through slots 46,formed in the slides 21. Disposed in the outer margin of the sash plates31, recesses 48 may be formed which are so positioned that when the sashplates are vertically disposed their base forces the pins 44 rearwardlyagainst the tension of the member 43, but when the sash plates 31 aremoved forwardly at an angle to its slide 21 the pins are also movedforwardly by the springs 43, which support them.

Secured against the frame 10 and within the channels formed by theslides 21, are catches 49 having slots 50 formed therein in suchrelation to the pins 44 as to receive the pins when the sash 33 ispivoted on the pivot pins 42 and both the sash and the sash plates 31are elevated. When the sash is parallel with the sash plates 31, thepins 44 will not be engaged by the slots 50 because the innerextremities of the recesses 48 so hold the pins against the springs 43that they pass beyond the catches 49.

Disposed on the inner side of the sash plates 31 and, intermediate theirends, in depressions formed by the partial removal of ribs 30a, are arms52, each arm having a sliding membr 53 pivotally mounted at one end, asindicated at 54, and being pivotally mounted at the opposite end of theslides 21, by means of a bolt 56. The arms 52 are spaced from the slides21 at their points of attachment thereto a sufficient distance to allowthe sash plates 31 to fit between slides 21 and the arms 52. Slots 57 ineach of the sash plates 31 are adapted to receive the bolts 56. The armsare so placed that, in the normal position, the arms are disposedbetween the sash plates and the sash as shown in Fig. 7, with a flangeportion 58 of the slide members 53 adapted to travel in a groove 59 inthe sash 33 as indicated in Fig. 5.

As shown in Figs. 4 and 6, safety locking devices 61 are provided tomaintain the sash and sash plates in an angular position for ventilationand prevent the sash from being inadvertently opened to a horizontalplane. However, the sash 33 and sash plates 31 may be opened to ahorizontal plane as shown in dot-and-dash lines in Fig. 4, as willhereinafter be apparent.

As shown in Figs. 6 and 7, each locking device 61 may be provided with alever member 62, pivotally mounted on the outer face of the portion 23of the slide 21, by a bracket 63 secured to the portion 23. The member62 is provided with an angularly disposed portion 64.adjacent one endthereof, said portion extending rearwardly with respect to the frame,and at the opposite end thereof terminates in a portion 65 disposed atright angles thereto, the portion 65 terminating in a wedge shapedportion 66, adapted to fit in openings 67 and 68 in the slide 21 andsash plate 31 respectively. The portion 62 is normally held incontacting relation with the outer surface of the arm 52, by means of aspring 69, of any suitable construction, disposed adjacent the portion64. When opening the window for ventilation the arm 52 moves inwardlyuntil the portion 66 fits into an opening 71 of the arm 52, which limitsthe movement of the sash.

When releasing the locking device 61 from engagement with the arm 52,for opening the window to a substantial horizontal plane, it isnecessary to move the slide 21 and sash 33, upwardly in a vertical planeuntil the angular portion 64, of the member 61, contacts with a surface'72 (Fig. 8), of a flanged member 73, secured to the window frame 10 anddisposed at a predetermined distance above the locking device 61. Inoperation the window is raised with the portion 64, first contactingwith a curved surface '74, of the member '73, after which the member 64moves along said curved surface until the portion 64 contacts with thesurface 72, which forces the portion 64 inwardly until the lever 62 isdisposed in the position shown in dot-and-dash line in Fig. 6. As shownin Fig. 6, the wedge shaped portion is withdrawn from the opening 71 ofthe arm 52 which, under normal conditions, would allow the sash toassume a horizontal position, but because of the device hereinafterdescribed the sash is prevented from doing so.

In order to guard against accident and to pro vide a device for lockingthe window in a partially open position, the sash 33 is provided withlocking devices '76 one of which is arranged on each side of the windowadjacent the upper extremity thereof. Openings 176 are formed in eachside of the sash 33 for the reception of the locking devices 76, each ofthe openings being formed by cutting away a part of a rib portion 1'77which separates two channels 178 formed in each edge of the sash edges,and extending longitudinally thereof.

At opposite extremities of the openings 176 the rib portions 177 arenotched as indicated at 179 to provide steps 181 upon which latchingunits 78 of the locking devices 76 are rigidly secured by screws 183extending through the opposite extremities of the latching units andinto the steps 181. The latching units 78 comprise bars 77 partiallyfilling and substantially closing the openings 176 and on the inside ofwhich leaf springs 80 and 187 are secured by screws 186 between the barsand the steps 181 at the lower extremity of the openings 176. The upperextremity of each of the leaf springs 80 has rigidly secured therto, bymeans of a screw 185, a pin 82 which projects through a transverselyformed opening 188 in each of the bars 77 and into aligned openings 84,85 and 86 formed in the arms 52, the sash plates 31 and the sides 21respectively. The openings 84 in the arms 52 are somewhat large for thepins 82 as is indicated 'at 189 in Fig. 11 for a reason which willhereinafter be set forth.

Semi-cylindrical openings 191 are formed in the bars 77 in transverserelation to the openings 188 and directly beneath the latter.Semi-cylindrical cams '79 disposed beneath the springs and 187 in thesemi-cylindrical openings 191 are rotatable therein by shanks 192 formedintegrally between the cams '79 and operating handles 90 for thelatches. The shanks 192 extend through openings 193 formed between theopenings 176 and the front side of the sash 33. In these openings aredisposed annular flanges or bushings 194 in which the shanks 192arerot-atably mounted and which project inwardly from front plates 8'?secured on the front of the sash 33 by screws 196. The inner extremitiesof the flanges 194 are provided with arcuate notches 88 which cooperatewith pins 89 extending though the shanks 192 to limit the possiblerotation of the handles 99 and consequently the rotation of the cams'79.

It is apparent that rotation of the cams '79 will progressively removethe pins 82 from the openings 86, and 84 in the slides 21, the sideplates 31 and the arms 52 respectively.

In operation the sash 33 may be opened either vertically or by angularmovement thereof as desired.

In opening the sash vertically it is necessary only to lift upon anyconvenient part of the sash, and the sides 21, the sash plate 31 and thesash 33 all will move upwardly as a unit.

In the event it is desired to open the sash to any desired extent byangular movement thereof, the handles are simply moved inwardly at thebottom until the pins 82 are withdrawn from the openings 86 in theslides 21. The top of the sash is then pulled outwardly, as indicated inFig. 4, until the wedge shaped portions 1 66 of the members 61 engagethe openings 71 in the arms 52. This limited angular movement of thesash disengages the pin 44 from the openings 48 in the sash plates 31and permits the pins to move under the influence of the springs 43 intoa position just beneath the catches 49.

The sash 33 is then elevatedto a slight extent and so consequently arethe slides 21 elevated until the pins 44 carried thereby slide withinthe notches 50 in the catches 49 which are secured to the frame 10 ofthe window. The sash, the

slides, and the sash plates cannot then be further elevated butsimultaneously with the movement of the pins 44 into the openings 50,the angular portions 64 of the latching members 61 engage the slopingsurfaces 74 of the earns 72 and so move the latching members 61 as torelease the wedge shaped portions 66 thereof from the openings 71 in thearms 52. When this event occurs the sash 33 will drop slightly byangular movement upon the pins 42 until the portions of the arms 52 atthe extremities of the openings 84 limit any further movement of thesash.

In this position the window can be moved neither angularly norvertically ,except from within the room, as will be hereinafterdescribed, and therefore the window may be said to be locked in apartially opened position.

The sash, however, may be further opened into the position indicated bythe dot-and-dash lines in Fig. 4 simply by further turning the handles90 inwardly until the pins 82 are entirely removed from the openings 85and 84 in the sash plates 31 and the arms 52. This removal of the pins82 from the aforesaid openings entirely releases the arms 52 and permitsthe sliding members 53 to move until they engage the oppositeextremities of the grooves 59 in which they are mounted.

To close the window the sash 33 is again pivoted on the pins 42 until itassumes a vertical position and then is pushed downwardly.

From the foregoing description it is apparent that I have provided animproved window construction, one in which the window cannot beinadvertently opened, thus providing a window that is more efiicientthan the window heretofore employed. In addition, by the combination ofparts and features of construction above described I have provided awindow in which certain portions thereof co-act to provide anexceptionally efiicient weatherproof window.

While I have shown in the drawings a particular illustrative view of myinvention, and have described the elements and functions thereof indetail, various modifications may be made in the same, and in thevarious features of construc tion, without materially changing theinvention therein, and formal changes may be made in the specificembodiments of the invention described, without departing from thespirit or substance of the broad invention, the scope of which iscommensurate with the appended claims.
